Will a cassette with 32 teeth work with a 105 compact chainset?
Front is 50/34
Front is 50/34
Any point. A 34 x 30 vs a 34 x 32 will make very little difference in gear inches.
Gear ratio for 34 x 32 is 1.06, for 34 x 30 it's 1.13 and for 34 x 28 it's 1.21. Basically the 32 over the 30 is as much a step as going for 30 over a 28, so actually worth it if you need that extra gear.
Have a look on the back of the rear derailieur, you should see one of these numbers...
5600....32 wont work
5700....32 wont work
5701....32 will work
58xx....32 will work
The length of the derailiure is to do with the front chainset. A tripple needs a long one to take up the extra slack.
A double will work with long or short, but best With the short one... which they call the medium.
Hope that helps.
Is 32 recommended for 5701 or is it something you have tried and was ok?
Reason I ask is that I have 5701 and just switched 12-28 to 12-30 and when I checked 30 was the max'.
